The 10 Best BJJ Rash Guards For 2024: A Complete Buyer’s Guide

Advertising Disclosure

If you’ve ever stepped foot inside a Brazilian jiu-jitsu (BJJ) gym, you’ve most definitely seen those skin-tight, often colorful shirts that grapplers wear — a rash guard. BJJ Rash guards are a necessary part of every BJJ player’s training apparel, whether they do gi or no-gi jiu-jitsu.

With that in mind, we’ve brought jiu-jitsu players this complete buyer’s guide to the best rash guards on the market, from budget options to top-of-the-line. Also, check out our recommendations for the top 10 rash guards.

Why wear a rash guard?

Rash guards protect the skin

First and foremost, the main purpose of a rash guard is in its name: it protects against rash, or more specifically, mat burn. The smooth, thin layer of material that makes up the rash guard protects grapplers from cuts and abrasions that happen when the skin rubs against the mat or inside of the gi. Taking that one step further, because rash guards protect the skin against abrasions, they also lower the likelihood of infection.

More than just no-gi apparel, rash guards can and often should be worn under a gi top. Not only will the rash guard prevent skin abrasions and therefore infection, but wearing a rash guard under the gi also limits skin-to-skin contact, which lowers the chances of ringworm and other skin conditions spreading among grapplers.

BJJ Rash guards make rolling easier

Compared to regular cotton t-shirts, rash guards make “rolling” (jiu-jitsu sparring) much easier. Whereas cotton t-shirts will stretch and become looser as the grappler sweats, the polyester/spandex blend that makes up most rash guards will stay fitting snugly throughout every training session. This avoids a common problem when rolling in a t-shirt: feet and hands get stuck in the shirt during a roll. And, as an added bonus, rash guards are less likely to hold the smell of sweat, making it much easier to avoid the dreaded funk.

Compression supports muscle recovery

Finally, rash guards may actually help your performance and recovery. A study published in Sports Medicine found that compression apparel — like rash guards — can lead to a slight improvement in muscle endurance, as well as reduced muscle pain and inflammation. If there is one thing grapplers know, it’s muscle pain and inflammation, and a quality rash guard could reduce that.

What are the IBJJF guidelines on rash guards?

The IBJJF has strict rules when it comes to rash guards. According to Rule 8.1.3, male competitors are not permitted to wear a rash guard under their gi. However, Rule 8.1.4 states that female competitors must wear a rash guard under their gi.

In no-gi competitions, the rash guard must comply with specific requirements. The IBJJF states that “both genders must wear a shirt of elastic material (skin tight) long enough to cover the torso all the way to the waistband of the shorts, colored black, white, or black and white, and with at least 10% of the rank color(belt) to which the athlete belongs. Shirts 100% the color of the athlete’s rank (belt) are also permitted.”

The qualities of a good rash guard

Type of stitching

Because the rash guard will fit tight against your skin, the type of stitching used is crucial. Poor or weak stitching will not only increase the chances that the garment rips, but will also irritate the skin.

For the best rash guard, look for one with flatlock stitching. Whereas normal stitching using a single thread to join two pieces of fabric will create overlap between fabric, flatlock stitching eliminates this overlap by creating a smooth, continuous seam that won’t rub or irritate the skin. Moreover, flatlock stitching creates a stronger seam, which will extend the life of your rash guard.

Flatlock stitching creates a flat seem that won’t irritate the skin

Type of fabric

Obviously, the material that makes up your rash guard is important. Most rash guards are made of a polyester blend, typically with spandex or elastane. For BJJ, look for a material that is 80-95% polyester; any more polyester than that, and your rash guard likely won’t hold its shape for very long and could be too light for everyday training. The more spandex or elastane there is in the rash guard material, the thicker and more durable the garment will be. However, be wary of a rash guard that is more than 20% spandex — this could be too heavy for jiu-jitsu rolling.

Ranked or not?

As noted above, the IBJJF has strict requirements for no-gi apparel. If you’re planning to compete in a no-gi IBJJF competition, make sure your rash guard complies with the requirements of your rank. Ranked rash guards will come in the five colors of the belts — white, blue, purple, brown, and black — and will clearly state that they are approved for IBJJF competition.

Because they don’t have to comply with IBJJF requirements, un-ranked rash guards are often more unique in design, allowing you to show more of your personality and taste.

Sublimated graphics

The vast majority of rash guards on the market have sublimated graphics. This means that, rather than graphics that are ironed or sewn onto the garment, the graphics are a part of the material. This is crucial for BJJ practitioners because graphics that are not sublimated will quickly peel away from the fabric and fade after just a few hard rolling sessions.

In short, if you find a rash guard that does not have sublimated graphics, look elsewhere.

Elastic waistband

One feature of a quality rash guard that most people don’t consider is an elastic (or rubber) waistband. This is a crucial feature for jiu-jitsu practitioners because, without a waistband that fits tightly, the rash guard will ride up during a roll. Many rash guards that are not made specifically for BJJ won’t have an elastic waistband.

Some of the top rash guards also have elastic around the sleeves, which prevents the sleeves from riding up during a roll.
